2. Evaluate the cortical response to the task-based home therapy program. Correlates of task-based adaptation from pre- to post-training will be assessed using fMRI. H2: Greater activation (intensity and volume) in the primary motor cortex (M1) and sensory cortex will translate to increased voluntary activation of the transferred Br in pinch compared to elbow flexion. Task-based training outcome measures will include isometric pinch force magnitude, EMG quantification of Br activation in pinch and elbow flexion.
